mtd: Add new SmartMedia/xD FTL
This implements new readwrite SmartMedia/xd FTL.
mtd driver must have support proper ECC and badblock verification
based on oob parts for 512 bytes nand.
Also mtd driver must define read_oob and write_oob, which are used
to read and write both data and oob together.

This enables read only access to SmartMedia formatted NAND
flash. You can mount it with FAT file system.

+ This enables new and very EXPERMENTAL support for SmartMedia/xD
+ FTL (Flash tanslation layer)
+ Write support isn't yet well tested, therefore this code IS likely to
+ eat your card, so please don't use it together with valuable data.
+ Use readonly driver (CONFIG_SSFDC) instead.

+ Very old SmartMedia cards need ECC to be calculated in the FTL
+ Such cards are very rare, thus enabling this option is mostly useless
+ Also this support is completely UNTESTED.
